For those who don't want to read the whole article here are the key passages:

Though the decline of the humanities is getting a lot of attention now,
the major drop in enrollments happened between 1970 and 1985. Humanities enrollments
dipped from 17.2 percent of all degrees in 1967 to around seven percent
in the early 1980s. In 2011, humanities degrees still constituted 6.9
percent of all bachelor's degrees. In other words, the decline
stabilized ten years before current freshmen were even born.

So the rhetoric of a deep crisis in the humanities does not bear out in
the numbers. As overall enrollment has increased at institutions of
higher education, very similar percentages of the college-age population
have graduated with a degree in English over the past twenty years. In fact, there were proportionally more English majors amongst 21-year-olds in 2011 than in 1981.

As Ben Schmidt,
assistant professor of history at Northeastern University, has shown in
a series of great graphs, women's choices of major really explain most
of the drop. Starting in the late 1970s, women became the majority of
the undergraduate student body at colleges and universities in the
United States. By the 2000s, women made up around 57 percent of undergraduates. Women's decisions became increasingly important, and those choices started to change radically.

Some commentators
have argued that women should turn to STEM subjects to acquire those
capabilities and to secure better pay and professional options. Do we
need more women to study tech subjects? Of course. In 2011, women formed
only 27 percent of all workers in STEM jobs that generally offered higher than average pay. But others have shown that humanities graduates face no worse unemployment rates than computer scientists or economists.

So there you have it, it doesn't matter what you major in, just as long as you can do things for your employers!
